ABSTRACT

In order to study the battery performance, putting forward a kind of two order RC equivalent circuit model, measuring static and transient data by HPPC test, fitting the relationship between open circuit voltage and state of charge (SOC), analyzing system identification of the dynamic parameters with MATLAB tool. Finally, by comparing the simulation data with the test data, the model is correct and feasible.

Keywords:

Battery, dynamic model, open circuit voltage, state of charge (SOC), system identification.
